PORTABLE sTovE AND ovEN.

SPECIFICATION forming part of Letters Patent No. 329,783, dated November3, 1885.

Application filed April 29, v1895. Serial No. 163,827. (No model.)

y portable combined stoves and ovens, and is designed for use in ldirectconnection with an ordinary cooking-stove, or independently of saidcooking-stove, in connection with either the chimney or the stove-pipeof said cookingstove in the usual way, or out of doors as a camp-stove.

My invention consists in certain features hereinafter described, andpointed out in the claims. l

Figure 1 is a vertical central section of the portable combined stoveand oven. Fig. 2 is a view of the portable combined stove and oven inperspective. Fig. 3 is a view in perspectiveof the double damper.

A isthe portable combined stove and oven provided with the draft-openingm and the pot-holes f and'g.

The heating chamber or oven E is provided with double walls c and d onfour sides thereof, which walls form the flue-space b. Said flue-spacehas two escape-openings, h and j,

and is deepened or enlarged at a point above' the oven to form thecombustion-chamber a.

The two escape-openings hand j are to per` opening h there is a doubledamper, C, con

sisting of two plates, k and Z, connected by a portion of the handle n.The plate k is of slightly greater height than the flue-space beneathvthe oven, extends transversely across said nue-'space from side toside, and is at right angles to the other plate, Z, which is ofsufficientsize to coverthe opening h. Said double damper slides on thebottom of the lower fluespace, and when its handle is pushed in untillthe upper edge of the plate k strikes against the inner upright wall ofthat portion ,of the flue-space b which is between the opening h andtheexit the said flue-space is closed by said plate, while at the same timethe plate Z is moved out of coincidence with the opening h, and thuspermits the products of combustion to pass through said opening oneither sideof that part of the handle n which connects said plates; or,if said double damper be pulled out until the plate k shall be inContact with the outer upright wall of that portion of the nue-spacewhich is between the opening h and the exit j, there will be anunobstructed passage through the entire nue-space from vthecombustion-,chamber a to the exit j, while at the same time the plate Zwill coincide with the opening h and said opening will then be closed. Yl

When it is desired to use the portable stove in connection with theordinary cooking'stove, the said portable stove is placed thereon, andthe opening'h made to coincide with one of its pot holes. The air tovsupport combustion enters through the draft-opening m, and the productsof combustion escape through the due-'space b into the ordinarycookingstovc by means of the escape-opening 71J and the pothole t ofsaid cooking-stove. At this time the double damper C is pushed in untilits plate 7c closes that portion of the flue-space between the opening hand the exit j when the plate Z is out of coincidence with the openingh, and the products of combustion, being prevented by the plat-e k fromcontinuing their course from the combustion-chamber a` around vthe oven,escape through the opening h and the pot-hole t of the cooking-stoveinto the stove; but when it is desired to use the portable stoveindependently of the ordinary cookingstove the damper C is pulled outuntil its plate k comes in contact with the outer upright wall of thatportionv of the flue-space which isbetween the opening h and the exit j,when there will be an unobstructed passage through the entire length ofthe fine-space, and the. opening h being closedl by the plate Z of thedamper C, the products of combustion will pass from the'combustion-chamber a through the ,fluespace b around theheating-chamber and escape through the exit j, by means of a pipe, intothe chimney or stove-pipe of the cookingstove, it' used indoors,'or intothe open air if used outdoors.

Having thus-fully described my invention, what I claim asmy invention,and desire to secure by Letters Patent, is

1. A portable .stove which consists of an IOO,

oven `having double walls which forni a flucspace around the same, saidliuc-space being enlarged 0r deepened at a point above the oven to forma combustioli-chamber, and provided with an escape-orifice through thelower outer wall of the said oven, substantially as described.

2. A portable stove which consists of au oven having double walls whichform a fluespaee around the same, said liuc-space being enlarged ordeepened at a point above the oven to form a combustion-chamber, andprovided with one escape-orilice through the lower outer Wall of thesaid oven, and with' another at the end thereof farthest from thecombustion chamber, substantially as described.

3. The coinbnatouof the oven E, having the surrounding flues b and theescape-openings h andj, with the damper C, located in the flueb belowthe oven, and having the plates la and Z, for preventing the escape ofthe products of combustion through either of said openings, as desired,substantially as described.
